(13) Adjust A1R7 100V ADJ (fig. 1) to obtain an indication of 80.00 on TI (R).
(14) Set RANGE switch to 1000 V.
(15) Adjust calibrator for an output of 800.00 V.
(16) Adjust A1R8 1000V ADJ (fig. 1) to obtain an indication of 800.00 on TI (R).
(17) Adjust calibrator for a negative output of - 8.000 V.
(18) Set RANGE switch to 10 V.
(19) Adjust INT CHECK 8000 adjustment to obtain an indication of -8.000 on TI (R).
(20) Press and hold INT CHECK 8000 pushbutton.
(21) Adjust A3R60 -8.000 REF ADJ (fig. 1) to obtain an indication of -8.000 on TI (R).
Release INT CHECK 8000 pushbutton.
NOTE
If plug in model 3445A go to paragraph 11, for 3444A continue
with next step (22).
(22) Adjust calibrator output to standby and remove. Short TI INPUT terminals.
(23) Set RANGE switch to 100 MV and adjust front panel ZERO adjust to obtain
an indication of 00.00 on TI (R).

(26) Adjust calibrator for an output of 800.0 mV.
(27) Adjust A2R36 (fig. 1) to obtain an indication of 800.0 (R).
(28) Set calibrator for negative output and repeat (26) above.
(29) If required, readjust A2R36 and repeat (25) through (28) above until TI
indicates between 799.9 and 800.1 for both positive and negative outputs of calibrator.
(30) Connect calibrator for positive output.
(31)
